GPA 2.1 Feature Highlight: Buffer Histograms

GPA 2.1 includes a feature to allow you to better view render targets and textures. Let's say you have a texture with a very narrow dynamic range, all values in the texture are nearly white. When you select this texture to view, by default - it looks white The GPA histogram feature allows you not only to see where the data falls in any buffer, but also to increase the dynamic range of the buffer for viewing purposes. To increase the dynamic range, simply click the auto-clamp button at the top of the histogram panel, or manually move the highlights/shadows sliders within the histogram itself.

Within the histogram panel, individual color channel options are also available.

To make the histogram panel visible, simply double click on the panel pull out slider on the right side of any render target or texture. You can also manually click and drag to pull it out or resize it.
